Pin Descriptions
Pin(s)
Name
Description
Application Information
1
SW
Switch pin
Connect this pin to the output inductor and Schottky diode.
2
BOOT
MOSFET drive bootstrap pin
Connect a 10 nF ceramic capacitor from this pin to SW.
3
DIM
Input for PWM dimming
Connect a logic-level PWM signal to this pin to enable/disable the
power FET and reduce the average light output of the LED array.
4
GND
Ground pin
Connect this pin to system ground.
5
CS
Current sense feedback pin
Set the current through the LED array by connecting a resistor from
this pin to ground.
6
RON
On-time control pin
A resistor connected from this pin to VIN sets the regulator controlled
on-time.
7
VCC
Output of the internal 7V linear
regulator
Bypass this pin to ground with a minimum 0.1 F ceramic capacitor
with X5R or X7R dielectric.
8
VIN
Input voltage pin
Nominal operating input range is 6V to 42V (LM3402) or 6V to 75V
(LM3402HV).
DAP
GND
Thermal Pad
Connect to ground. Place 4 to 6 vias from DAP to bottom layer ground
plane.
